摘要
智能化开采是是世界煤炭技术革命的主流方向和我国煤炭企业转型发展的必然趋势,也是“十四五”乃至今后一个时期国家煤炭工业高质量发展的重要支撑,依托“智能+”实现煤炭的高质量开发是智能化开采的目标和可持续发展的内在动力。布置超长工作面可实现三提升和三降低,即绿色开采水平、产能、开采效率的提升和煤炭损失、采掘接替矛盾、成本支出的降低。国外超长工作面成功经验证明增大工作面长度是可行且有益的;受限于装备能力、智能化配置和管理水平目前我国工作面普遍在350m以下,与国际一流水平存在一定差距。根据中厚煤层小采场开采效益较低的现状,针对工作面加长后顶板控制理论与技术、工作面装备配套模式、安全保障技术、装备稳定性和可靠性较低等问题,结合小保当二号煤矿煤层赋存条件和产能目标,研究了超长工作面(工作面长度约450~480m)实现小保当煤矿中厚煤层年产8~10Mt/a的可行性和成套技术、装备与管理体系,实现工作面“顶板可控可预测”,“水源可控有保护”,“智能开采提效率”,“高速截运创效益”的目标,成套技术与装备达到国际领先水平。
Intelligent mining is the mainstream direction of world coal technology revolution and the inevitable trend of transformation and development of Chinese coal enterprises.It is also an important support for the high-quality development of national coal industry in the"14th five year plan"and even in the future.Relying on"intelligent+"to realize high-quality development of coal is the goal of intelligent mining and the internal driving force of sustainable development.The layout of super long working face can realize three improvements and three reductions,namely,the improvement of green mining level,production capacity and mining efficiency,coal loss,mining replacement contradiction and cost reduction.The successful experience of foreign super long working face has proved that it is feasible and beneficial to increase the length of working face;limited by the equipment capacity,intelligent configuration and management level,the working face in China is generally below 350m,which has a certain gap with the international first-class level.According to the low mining efficiency of small stope in medium thick coal seam,aiming at the problems of roof control theory and technology,matching mode of working face equipment,safety guarantee technology,equipment stability and reliability,combined with the coal seam occurrence conditions and productivity target of xiaobaodang No.2 coal mine,the ultra long working face(working face length is about 450~480m)is studied to realize xiaobaodang coal mine The feasibility and complete set of technology,equipment and management system with an annual output of 8~10 MT/A in medium thick coal seam can achieve the goal of"controllable and predictable roof","controllable and protected water source","intelligent mining efficiency"and"high speed cutting and transportation to create benefits"and the complete set of technology and equipment has reached the international leading level.
